This data type is a container that stores information about a single property of a searchable object type. Each <b>[SoftLayer_Container_Search_ObjectType](/reference/datatypes/SoftLayer_Container_Search_ObjectType)</b> object holds a collection of these properties. Property information can be used for discovery of searchable data and for the creation or validation of object index search strings. Note that properties are only understood by the <b>[SoftLayer_Search::advancedSearch](/reference/services/SoftLayer_Search/advancedSearch)</b> method. Refer to the <b>advancedSearch()</b> method for information on using properties in search strings.
